Abstract
The utility model provides a floating coil displacement heat exchanger, which mainly comprises an end enclosure, a water tank, a coil and a multi-hole cylinder. The multi-hole cylinder is placed in the water tank, the coil is mounted in the multi-hole cylinder in a floating manner, and the end enclosure and the multi-hole cylinder are connected by a flange. Cold water in the multi-hole cylinder is heated by the floating coil, hot water forms jet flows at a relatively higher temperature when passing through small holes on the multi-hole cylinder and then enters a cold water zone inside a water tank casing, dead water zones in the water tank are eliminated, the flowability of the cold water in the water tank is improved, and the water temperature inside the water tank can be kept even; the floating coil has smaller constraint force and larger degree of freedom, the vibration induced by the fluid in the coil and the own thermal compensation capability of an elastic tube bundle ensure that the surface of a heat exchange tube is difficult to scale, and the heat transfer efficiency is improved; in addition, the end enclosure and the multi-hole cylinder are connected by the flange, thereby facilitating tube bundle assembly and overhaul.
Description
Technical field
The utility model relates to a kind of positive displacement coil heat exchanger, is mainly used in the heating of industry or bath water.Belonging to technical field of heat exchangers, is a kind of floating coiled pipe volumetric heat exchanger specifically.
Background technology
At present, common positive displacement and half-volume type heat exchanger mainly adopt the U type to restrain cold water in the heating water tank.Its major defect is:
1. have the slough in the water tank, it is inhomogeneous to be heated cold water temperature;
2. the easy fouling of heat exchange pipe external surface has increased dirtiness resistance, has reduced heat transfer efficiency;
3.U the type tube bank needs often to extract out to clean, and not only causes waste of manpower resource, has also reduced the service life of equipment to a certain extent.
Summary of the invention
The purpose of this utility model is at the above-mentioned shortcoming of existing volume, formula half volume heat exchanger, and a kind of floating coiled pipe volumetric heat exchanger is provided, and its heat-transfer effect is good, and is stable, can reduce the recondition expense of equipment effectively.
The purpose of this utility model is achieved through the following technical solutions:
A kind of floating coiled pipe volumetric heat exchanger comprises: end socket, water tank, coil pipe is characterized in that: a porous tube is arranged in the described water tank, and coil pipe floats and is installed in the porous tube.
To improvement of the technical scheme: adopt flange to connect between described end socket and the porous tube.
The utility model compared with prior art has following advantage and good effect:
1. the porous tube structure of the utility model introducing can be eliminated the slough in the water tank, improves the flowability of water tank inner cold water, guarantees even water temperature in the water tank.
2. the floating coiled pipe structure of the utility model employing can be removed the dirt of coil surface automatically, thereby effectively reduce dirtiness resistance, has improved heat transfer efficiency.
3. adopt vessel flange to be connected assembling of being convenient to restrain and maintenance between end socket and the porous tube.
Description of drawings
Fig. 1 is the structure chart of the utility model floating coiled pipe volumetric heat exchanger;
The specific embodiment
Referring to Fig. 1, the embodiment of the utility model floating coiled pipe volumetric heat exchanger comprises end socket 1, water tank 3, coil pipe 5, and porous tube 4, porous tube 4 are placed in the water tank 3, and coil pipe 5 floats and is installed in the porous tube 4, adopts flange 2 to connect between end socket 1 and the porous tube 4.
High-temperature mediums in the floating coiled pipe 5 with the heating of the cold water in the porous 4 after, hot water forms the higher jet of relative temperature during by the aperture on the porous tube and enters into cold water area in the tank shell 3.Because the density of hot water forms convection current less than the density of cold water between the hot water of rising and the cold water of decline, realizes the heat transmission between the hot water or cold water.
The restraining force of floating coiled pipe 5 is less, the free degree is bigger, the thermal compensation ability of vibration that tube fluid brings out and elastic tube bundle itself, make the heat exchanger tube surface be difficult to fouling, even cause the heat exchanger tube surface scale after a period of time out of service at equipment, after the equipment operation, also can remove automatically, improve heat transfer efficiency.
In addition, adopt flange 2 to connect assembling that this structure is convenient to restrain and maintenance between end socket 1 and the porous tube 4.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of having done, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
